Throughout the history of China, many emperors were inextricably linked to Emperor Yong of the former Dynasty Emperor Wen of Wei

In the early years of history, many emperors were officials in the former dynasty, and in the sixteenth year of Jian'an (211), Cao Pi served as a general and deputy chancellor of the five senses, and in the twenty-fifth year of Jian'an (220), Cao Pi succeeded him as a chancellor and king of Wei, and soon ascended the throne to establish the state of Wei. Her sister Cao Jie was the empress of Liu Xie, the Emperor of Han Xian, Cao Jie was of course dissatisfied with Cao Pi's approach, deposed Emperor Xian of Han, of course, her empress position was not secure, she reprimanded Cao Pi for usurping Han is a great rebellion, but because it is estimated that many people are Three Kingdoms, there is not much to say here, in short, Cao Pi ended more than 400 years of Han Dynasty, became emperor, that is, Emperor Wei Wen.

Liu Xie deposed as the Duke of Shanyang (present-day Jiaozuo), in order to protect himself, he sent his daughter Liu Man to the Wei Palace as a concubine, although Liu Man was not born to Cao Jie, but still considered his stepmother, Cao Jie was not very willing, because he and Cao Pi were sisters and brothers, marrying his stepdaughter to Cao Pi, but he was one generation older than Cao Pi, what to call him? Liu Xie hurriedly retorted: Now in order to eliminate suspicion and save his life, the other two daughters born to Cao Jie were sent to the palace, Liu Xie even deceived and coaxed the other two daughters to be concubines, they could enter the palace without worry about food and clothing, ventilated messages, and taught etiquette, Cao Pi also agreed "informally", named Liu Man as princess of Changle, it is said that Liu Xie practiced medicine in his later years, Cao Jie was tolerant and charitable, and life was good.

And the Tang Dynasty Emperor Li Yuan also had similar things, and he had time to say something else.
